Overview

By default, when Hugo renders a page, the resulting URL matches the file path within the content directory. For example:

content/posts/post-1.md → https://example.org/posts/post-1/

You can change the structure and appearance of URLs with front matter values and site configuration options.

Front matter

slug

Set the slug in front matter to override the last segment of the path. The slug value does not affect section pages.

{{< code-toggle file=content/posts/post-1.md fm=true >}} title = 'My First Post' slug = 'my-first-post' {{< /code-toggle >}}

The resulting URL will be:

https://example.org/posts/my-first-post/

url

Set the url in front matter to override the entire path. Use this with either regular pages or section pages.

With this front matter:

{{< code-toggle file=content/posts/post-1.md fm=true >}} title = 'My First Article' url = '/articles/my-first-article' {{< /code-toggle >}}

The resulting URL will be:

https://example.org/articles/my-first-article/

If you include a file extension:

{{< code-toggle file=content/posts/post-1.md fm=true >}} title = 'My First Article' url = '/articles/my-first-article.html' {{< /code-toggle >}}

The resulting URL will be:

https://example.org/articles/my-first-article.html

In a monolingual site, a url value with or without a leading slash is relative to the baseURL.

In a multilingual site:

• A url value with a leading slash is relative to the baseURL.
• A url value without a leading slash is relative to the baseURL plus the language prefix.

Site type	Front matter url	Resulting URL
monolingual	/about	https://example.org/about/
monolingual	about	https://example.org/about/
multilingual	/about	https://example.org/about/
multilingual	about	https://example.org/de/about/

If you set both slug and url in front matter, the url value takes precedence.

Permalinks tokens in front matter

{{< new-in "0.131.0" >}}

You can also use Permalinks tokens in the url front matter. This is typically used in cascade sections:

{{< code-toggle file=content/foo/bar/_index.md fm=true >}} title ="Bar" cascade url = "/:sections[last]/:slug" {{< /code-toggle >}}

Site configuration

Permalinks

In your site configuration, define a URL pattern for each top-level section. Each URL pattern can target a given language and/or page kind.

Front matter url values override the URL patterns defined in the permalinks section of your site configuration.

Monolingual examples

With this content structure:

content/
├── posts/
│   ├── bash-in-slow-motion.md
│   └── tls-in-a-nutshell.md
├── tutorials/
│   ├── git-for-beginners.md
│   └── javascript-bundling-with-hugo.md
└── _index.md

Render tutorials under "training", and render the posts under "articles" with a date-base hierarchy:

{{< code-toggle file=hugo >}} [permalinks.page] posts = '/articles/:year/:month/:slug/' tutorials = '/training/:slug/' [permalinks.section] posts = '/articles/' tutorials = '/training/' {{< /code-toggle >}}

The structure of the published site will be:

public/
├── articles/
│   ├── 2023/
│   │   ├── 04/
│   │   │   └── bash-in-slow-motion/
│   │   │       └── index.html
│   │   └── 06/
│   │       └── tls-in-a-nutshell/
│   │           └── index.html
│   └── index.html
├── training/
│   ├── git-for-beginners/
│   │   └── index.html
│   ├── javascript-bundling-with-hugo/
│   │   └── index.html
│   └── index.html
└── index.html

To create a date-based hierarchy for regular pages in the content root:

{{< code-toggle file=hugo >}} [permalinks.page] "/" = "/:year/:month/:slug/" {{< /code-toggle >}}

Use the same approach with taxonomy terms. For example, to omit the taxonomy segment of the URL:

{{< code-toggle file=hugo >}} [permalinks.term] 'tags' = '/:slug/' {{< /code-toggle >}}

Multilingual example

Use the permalinks configuration as a component of your localization strategy.

With this content structure:

content/
├── en/
│   ├── books/
│   │   ├── les-miserables.md
│   │   └── the-hunchback-of-notre-dame.md
│   └── _index.md
└── es/
    ├── books/
    │   ├── les-miserables.md
    │   └── the-hunchback-of-notre-dame.md
    └── _index.md

And this site configuration:

{{< code-toggle file=hugo >}} defaultContentLanguage = 'en' defaultContentLanguageInSubdir = true

[languages.en] contentDir = 'content/en' languageCode = 'en-US' languageDirection = 'ltr' languageName = 'English' weight = 1

[languages.en.permalinks.page] books = "/books/:slug/"

[languages.en.permalinks.section] books = "/books/"

[languages.es] contentDir = 'content/es' languageCode = 'es-ES' languageDirection = 'ltr' languageName = 'Español' weight = 2

[languages.es.permalinks.page] books = "/libros/:slug/"

[languages.es.permalinks.section] books = "/libros/" {{< /code-toggle >}}

The structure of the published site will be:

public/
├── en/
│   ├── books/
│   │   ├── les-miserables/
│   │   │   └── index.html
│   │   ├── the-hunchback-of-notre-dame/
│   │   │   └── index.html
│   │   └── index.html
│   └── index.html
├── es/
│   ├── libros/
│   │   ├── les-miserables/
│   │   │   └── index.html
│   │   ├── the-hunchback-of-notre-dame/
│   │   │   └── index.html
│   │   └── index.html
│   └── index.html
└── index.html

Tokens

Use these tokens when defining the URL pattern. These can both be used in the permalinks configuration and in the front matter url.

:filename

:year

The 4-digit year as defined in the front matter date field.

:month

The 2-digit month as defined in the front matter date field.

:monthname

The name of the month as defined in the front matter date field.

:day

The 2-digit day as defined in the front matter date field.

:weekday

The 1-digit day of the week as defined in the front matter date field (Sunday = 0).

:weekdayname

The name of the day of the week as defined in the front matter date field.

:yearday

The 1- to 3-digit day of the year as defined in the front matter date field.

:section

The content's section.

:sections

The content's sections hierarchy. You can use a selection of the sections using slice syntax: :sections[1:] includes all but the first, :sections[:last] includes all but the last, :sections[last] includes only the last, :sections[1:2] includes section 2 and 3. Note that this slice access will not throw any out-of-bounds errors, so you don't have to be exact.

:title

The title as defined in front matter, else the automatic title. Hugo generates titles automatically for section, taxonomy, and term pages that are not backed by a file.

:slug

The slug as defined in front matter, else the title as defined in front matter, else the automatic title. Hugo generates titles automatically for section, taxonomy, and term pages that are not backed by a file.

:filename

The content's file name without extension, applicable to the page page kind.

:slugorfilename

The slug as defined in front matter, else the content's file name without extension, applicable to the page page kind.

For time-related values, you can also use the layout string components defined in Go's time package. For example:

{{< code-toggle file=hugo >}} permalinks: posts: /:06/:1/:2/:title/ {{< /code-toggle >}}

Appearance

The appearance of a URL is either ugly or pretty.

Type	Path	URL
ugly	content/about.md	https://example.org/about.html
pretty	content/about.md	https://example.org/about/

By default, Hugo produces pretty URLs. To generate ugly URLs, change your site configuration:

{{< code-toggle file=hugo >}} uglyURLs = true {{< /code-toggle >}}

Post-processing

Hugo provides two mutually exclusive configuration options to alter URLs after it renders a page.

Canonical URLs

{{% note %}} This is a legacy configuration option, superseded by template functions and Markdown render hooks, and will likely be removed in a future release.

{{% /note %}}

If enabled, Hugo performs a search and replace after it renders the page. It searches for site-relative URLs (those with a leading slash) associated with action, href, src, srcset, and url attributes. It then prepends the baseURL to create absolute URLs.

<a href="/about"> → <a href="https://example.org/about/">
<img src="/a.gif"> → <img src="https://example.org/a.gif">

This is an imperfect, brute force approach that can affect content as well as HTML attributes. As noted above, this is a legacy configuration option that will likely be removed in a future release.

To enable:

{{< code-toggle file=hugo >}} canonifyURLs = true {{< /code-toggle >}}

Relative URLs

{{% note %}} Do not enable this option unless you are creating a serverless site, navigable via the file system. {{% /note %}}

If enabled, Hugo performs a search and replace after it renders the page. It searches for site-relative URLs (those with a leading slash) associated with action, href, src, srcset, and url attributes. It then transforms the URL to be relative to the current page.

For example, when rendering content/posts/post-1:

<a href="/about"> → <a href="../../about">
<img src="/a.gif"> → <img src="../../a.gif">

This is an imperfect, brute force approach that can affect content as well as HTML attributes. As noted above, do not enable this option unless you are creating a serverless site.

To enable:

{{< code-toggle file=hugo >}} relativeURLs = true {{< /code-toggle >}}

Aliases

Create redirects from old URLs to new URLs with aliases:

• An alias with a leading slash is relative to the baseURL
• An alias without a leading slash is relative to the current directory

Examples

Change the file name of an existing page, and create an alias from the previous URL to the new URL:

{{< code-toggle file=content/posts/new-file-name.md >}} aliases = ['/posts/previous-file-name'] {{< /code-toggle >}}

Each of these directory-relative aliases is equivalent to the site-relative alias above:

• previous-file-name
• ./previous-file-name
• ../posts/previous-file-name

You can create more than one alias to the current page:

{{< code-toggle file=content/posts/new-file-name.md >}} aliases = ['previous-file-name','original-file-name'] {{< /code-toggle >}}

In a multilingual site, use a directory-relative alias, or include the language prefix with a site-relative alias:

{{< code-toggle file=content/posts/new-file-name.de.md >}} aliases = ['/de/posts/previous-file-name'] {{< /code-toggle >}}

How aliases work

Using the first example above, Hugo generates the following site structure:

public/
├── posts/
│   ├── new-file-name/
│   │   └── index.html
│   ├── previous-file-name/
│   │   └── index.html
│   └── index.html
└── index.html

The alias from the previous URL to the new URL is a client-side redirect:

{{< code file=posts/previous-file-name/index.html >}}

<html lang="en-us"> <head> </head> </html> {{< /code >}}

Collectively, the elements in the head section:

• Tell search engines that the new URL is canonical
• Tell search engines not to index the previous URL
• Tell the browser to redirect to the new URL

Hugo renders alias files before rendering pages. A new page with the previous file name will overwrite the alias, as expected.

Customize

To override Hugo's embedded alias template, copy the [source code] to a file with the same name in the layouts directory. The template receives the following context:

Permalink

The link to the page being aliased.

Page

The Page data for the page being aliased.

[source code]: {{% eturl alias %}}
